Over the last few decades, nucleic acids (e.g., DNAs and RNAs) have proven to be an exceptionally versatile material beyond genetic information storage. As a sequence controlled polymer, they fold into a unique structure and create a variety of functionalities including molecular recognition, catalysis, construction of complex patterns, and even nanomechanical motions. Importantly, these synthetic constructs can be programmed to perform a wide range of molecular functions in a controlled manner. They offer unique capabilities with regards to the creation of molecular machines that can perform complex functions in the right order at the right time – this is a powerful feature that cannot be easily realized in other macromolecules. To fully realize this potential, my work has focused on the development of novel methodologies to generate nucleic acid-based multi-functional biopolymers and their applications. Specifically, in this presentation, I will introduce an innovative in vitro selection strategy enabling the discovery of nucleic acid nanostructures that undergo binding-induced structure-switching. I will subsequently show that the generated synthetic allosteric regulators perform useful molecular functions for diagnostics, imaging and targeted therapy applications. Furthermore, I will demonstrate a unique catalytic RNAs (ribozymes) that recognize and polymerize the targeted short RNAs by processive ligation events.
